It provides real-time measurement of the heater block or heatsink temperature, fundamental data used by the firmware to regulate heating resistance and trigger the machine's thermal safety features.\u003cbr\u003e\u003cbr\u003eAs an NTC (negative temperature coefficient) type with a nominal resistance of 100 kΩ, this sensor conforms to the profile expected by Prusa firmware, ensuring controlled regulation without software recalibration upon reassembly. Depending on the printer model, this thermistor is also used for heatsink monitoring on the XL.\u003c\/p\u003e\n\u003ch2\u003eImplementation\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eReplacement is necessary in case of inconsistent readings, thermal errors during printing, or physical sensor failure (wire breakage, insulation). The operation is performed with the printer off and the hotend cooled, following the procedure documented in the Prusa knowledge base (help.prusa3d.com), by selecting the relevant printer model and following the corresponding repair manual. The product is delivered with its M3×4 locking screw ready to install. After reassembly, check reading consistency during cold start and run a PID tune to validate thermal regulation stability.\u003c\/p\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003ePart Type\u003c\/th\u003e\n\n\u003ctd\u003eThermal probe (NTC thermistor)\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eNominal Resistance\u003c\/th\u003e\n\n\u003ctd\u003e100 kΩ\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eCable Length\u003c\/th\u003e\n\n\u003ctd\u003e115 mm\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eSensor Type\u003c\/th\u003e\n\n\u003ctd\u003eNTC (negative temperature coefficient)\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eContents of delivery\u003c\/th\u003e\n\n\u003ctd\u003e1 NTC 100k 115 mm thermistor + 1 M3×4 locking screw\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eDocumentation\u003c\/th\u003e\n\n\u003ctd\u003eInstallation procedure at help.prusa3d.com (by printer model)\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eUsage\u003c\/th\u003e\n\n\u003ctd\u003eReplacement part \/ hotend or heatsink maintenance\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n  \u003ctr\u003e\n\n\u003cth\u003eBrand\u003c\/th\u003e\n\n\u003ctd\u003ePrusa Research\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\n\u003c\/table\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cul\u003e\n\n  \u003cli\u003ePrusa Research printers equipped with a Nextruder extruder\u003c\/li\u003e\n\n  \u003cli\u003eOriginal Prusa MK4 and MK4S\u003c\/li\u003e\n\n  \u003cli\u003eOriginal Prusa MK3.9 and MK3.9S\u003c\/li\u003e\n\n  \u003cli\u003eOriginal Prusa XL (heatsink temperature measurement)\u003c\/li\u003e\n\n  \u003cli\u003eOriginal Prusa CORE One, CORE One+ and CORE One L\u003c\/li\u003e\n\n  \u003cli\u003eNot compatible with earlier generations (MK3S, MK3, MK2.5S, MK2.5, MINI, MINI+, SL1, SL1S, CW1, CW1S) and with MK3.5, MK3.5S, HT90 or INDX models\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"Prusa","offers":[{"title":"Default Title","offer_id":56893893804376,"sku":"IDF__10601_IDS__1576","price":10.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0938\/8979\/0296\/files\/9e4ee773-c070-4777-821c-dc3866a2a049.jpg?v=1779700115","url":"https:\/\/3dprint.shop\/en\/products\/thermistor-ntc-100k-115-mm","provider":"3dPrint.Shop","version":"1.0","type":"link"}
